Salt plantain seeds need frying. Salt plantain seed is a dry and mature seed of plantain, and seed Chinese medicine contains a lot of mucus. When they are mixed with decoction, they tend to stick to the bottom of the pot, making the medicine paste and the liquid medicine turbid, so it is a better method to fry the salt plantain seeds.
Decocting medicine is to put the medicine into a thin cotton bag with primary color and decoct it. Specifically, pollen, fine seeds and fine powder drugs should be fried, because they are easy to float on the water surface, which is not conducive to decoction, such as pollen typhae, lepidium seeds and talcum powder. Drugs containing more starch and mucus should be fried, because it is easy to stick to the pan for gelatinization and coking, such as plantain seeds; Fluffy medicine should be fried, because it is difficult to filter out. If it is mixed with liquid medicine, it will irritate the throat, such as Inula.
